Filling up at Sam’s Club can save you serious money — but the process trips up a lot of people. Wrong card, wrong app setting, or a surprise $100 pump cutoff can turn a quick stop into a headache. This guide walks you through exactly how to get gas at Sam’s Club the smart way, from membership requirements to payment tricks that keep more money in your pocket.
Do You Need a Membership to Get Gas at Sam’s Club?
Yes — in most cases, you need an active Sam’s Club membership to buy gas. The pump asks for your membership credential before it lets you pay for anything.
Sam’s Club offers two main tiers:
- Club membership — the standard option
- Plus membership — premium tier with extra perks and higher Sam’s Cash rewards
When you pull up to a pump, the screen prompts you to verify your membership first. You can do that with a physical membership card or through the Sam’s Club app. If your membership is expired, the pump rejects you on the spot — no workarounds.
Can Non-Members Get Gas at Sam’s Club?
Sometimes. There are two main exceptions:
- Co-located stations — Some Sam’s Club fuel centers sit on the same property as a Walmart store. Because Walmart is open to the public, those pumps are often configured to allow non-member access.
- State laws — Certain states legally prohibit restricting fuel sales to members only. In those locations, Sam’s Club must let anyone buy gas.
If you’re a non-member who does get access, expect to pay around 5 cents more per gallon. The system automatically applies a surcharge to preserve the membership price advantage.
What About Using a Sam’s Club Gift Card Without a Membership?
This one’s complicated. The pump technically accepts gift cards, but it still asks for a membership credential first. Historically, fuel attendants carried a master override card to help gift card users bypass this step. That practice has been largely phased out at most locations after corporate audits found people were using gift cards to dodge the annual fee. Don’t count on this working.
How to Get Gas at Sam’s Club With a Walmart Plus Membership
Here’s a game-changer most people don’t know: you don’t need a Sam’s Club membership if you have Walmart Plus.
Walmart Plus members get full access to Sam’s Club fuel prices. The process runs entirely through the Walmart app — no physical card needed.
Here’s how it works:
- Open the Walmart app on your phone
- Tap the menu for digital services
- Select “Member prices on fuel”
- Choose “Pay at the pump”
- Scan the QR code on the pump screen with your phone camera
- The app authenticates your Walmart Plus membership and unlocks the pump
Once the screen confirms authorization, you pick your fuel grade and start pumping. Your payment method stored in the Walmart app handles the rest automatically.
This cross-membership access is one of the most underused perks in the Walmart ecosystem. If you already pay for Walmart Plus, you’re leaving money on the table by going to a pricier gas station.
How to Use the Sam’s Club App to Get Gas (Scan & Go)
Sam’s Club rolled out its Scan & Go fuel system across 500+ stations, and it’s the fastest, safest way to fill up.
Step-by-Step: Using Scan & Go at the Pump
- Pull up to any available pump
- Open the Sam’s Club app
- The app uses your location to confirm you’re at a fuel center
- Navigate to the fuel section and activate the scan feature
- Scan the QR code on the pump’s screen
- The app links to your account, processes your saved payment, and unlocks the pump
- Lift the nozzle, pick your grade, and start pumping
That’s it. No card swiping, no keypad touching, no dealing with a broken receipt printer.
Why the App Is Better Than the Card
Using a physical card at an outdoor pump comes with real risks. Skimming devices — tiny hardware criminals attach to pump readers — are a widespread problem at outdoor terminals. The Scan & Go system bypasses the physical reader entirely, so there’s nothing to skim.
You also get a digital receipt sent to your email automatically. Outdoor receipt printers break constantly — paper jams, empty rolls, broken mechanisms. With the app, your record exists whether the printer works or not.
App Troubleshooting Tips
The app needs a stable data connection to work. Metal pump canopies can weaken your cell signal. If the app stalls or the QR scan fails, try this:
- Connect to the store’s Wi-Fi — many Sam’s Club locations broadcast a signal into the forecourt
- Update your app — outdated software can prevent the camera from launching, which blocks the scan entirely
- If all else fails, use your physical membership card as a backup

The Sam’s Club Credit Card: 5% Back on Gas
The Sam’s Club Mastercard is the highest-yield fuel card most drivers aren’t using. Here’s what it does:
- 5% cash back on gas — at Sam’s Club and most other gas stations
- That 5% applies to the first $6,000 in fuel purchases per year
- After $6,000, the rate drops to 1%
- Rewards are stored as Sam’s Cash, redeemable for merchandise, membership renewal, or cash
The card also works as your membership credential, so you’re swiping once instead of twice. For a driver using 15–20 gallons a week, the cash back from fuel alone can easily cover the entire annual membership fee.
The Pre-Authorization Hold Problem (And How to Avoid It)
This catches people off guard constantly. When you swipe a card at a gas pump, the station doesn’t know how much fuel you’ll pump yet — so it places a temporary hold on your account to cover the potential total.
At Sam’s Club, that hold is typically $100 to $125. That money is frozen in your account the moment you swipe, even if you only pump $40 worth of gas.
Debit Cards: The Real Risk
With a debit card, the hold pulls directly from your checking account’s available balance. If you have $150 in your account and the pump places a $100 hold, you effectively have $50 to spend — even before a single gallon flows.
That frozen balance can sit there for 48 hours to 7 business days depending on your bank. If you’re not expecting it, this leads to overdraft fees or declined purchases elsewhere.
Some states have pushed back. Connecticut, for example, has legislation requiring disclosure when debit holds exceed certain thresholds — but enforcement is tricky because the holds are technically set by the card networks, not the merchant.
Credit Cards: The Smarter Option
With a credit card, the pre-authorization hold is often just $1. The card network checks that your account is active, and the actual charge posts a day or two later. Your checking account stays untouched the entire time.
Bottom line: if you have the choice, use a credit card at the pump. Better yet, use the Sam’s Club Mastercard and earn 5% back while you’re at it.
The $100 Pump Cutoff — What’s Happening and What to Do
The pump shuts off automatically when your total hits $100. This isn’t a glitch. It’s a fraud prevention feature hard-coded into the pump software to limit losses from stolen cards and equipment failures.
For most passenger cars, $100 covers a full tank. But if you drive a large truck, RV, or tow a trailer, your tank might need $150, $200, or more.
Workarounds for Large Vehicles
- Go inside the store — if there’s an indoor cashier or kiosk, you can pre-pay a specific higher amount (like $250) that overrides the automated limit
- Run a second transaction — return the nozzle, re-authenticate, and start again. It’s frustrating but it works
- Be careful with debit — running two transactions means two separate holds on your checking account simultaneously. That’s up to $200 frozen at once. Use a credit card here
Sam’s Club Gas Station Hours
The fuel pumps run on a different schedule than the main warehouse. Here’s what to expect at most locations:
- Monday–Saturday: 6:00 AM – 9:00 PM
- Sunday: 9:00 AM – 7:00 PM
- High-traffic urban locations: some extend to 10:00 PM
These aren’t 24-hour stations. The pumps shut down electronically at closing time — full stop. Always check your specific club’s hours before an early morning or late evening fill-up.
Getting the Most Out of Sam’s Club Gas Prices
Sam’s Club gas typically runs 10 to 30 cents per gallon cheaper than nearby stations. For a driver burning 15–20 gallons a week, that’s $75–$300 in annual savings from fuel alone — often more than the cost of a base membership.
Here’s how to stack your savings:
- Get the Sam’s Club Mastercard — 5% back at Sam’s Club and virtually every other gas station
- Use Scan & Go — faster, safer, and you’ll never miss a receipt again
- Stick to credit, not debit — avoid the hold trap entirely
- Know your pump’s limit — plan ahead if you drive a large vehicle
- Check the app for fuel prices before heading out — prices vary by location and change daily
Between the per-gallon discount, the credit card cash back, and the Walmart Plus cross-membership option, there’s a combination here that works for almost every driver. You just need to know which tools to use.
